Problem 5 (20 points) The force shown in the figure below acts on a 0.44 kg object that moves along the x axis. Assume the force is a constant 0.70 N (to the right) from x = 0 m to x = 3.0 m. Assume the force then decreases linearly from 0.70 N at x - 3.0 m to O N at x - 7.0m. this is supposed to be in this is supposed to be a straight well line from 070 1 at 1= 30m to ON at x - 7.0m 0,80 Force F() 0.40 0.20 Position * (mm) 0.525 N at x = 4.0 m. A. (10) Suppose the object moves from x; = 1.0 m with an initial speed v; - 4.5 m/s, to x* = 4.0 m. What is the final speed of the object at x = 4.0 m? Assume F = B. (10) Suppose the object moves from x; - 2.7 m with an initial speed vi - 2.5 m/s, to x - 0.79 m. What is the final speed of the object at x = 0.79 m
